I wrote my PMP PBT exams on the 13th of May 2017, it appears the questions are now more wordy and technical, it took me the entire 4hrs to go through the whole 200 questions and no time to review my answers, the results arrived via email from PMI exactly 10 days after the exams. I thank God for success. My advice is that more updated material and simulators should be employed to prepare for the exams, as it appears the exams is now more difficult to pass as the profile of the certification has risen significantly over the years. The best way to really understand Project management from PMI's perspective is to read and understand the PMBOK, it's ok to read other materials first for base understanding, but you need the PMBOK to fine tune your knowledge (especially for ITTO) and be prepared for all kind of questions in the exams. All the best. Cheers
